I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.
View 6 Replieshow bad is this practice? I am having trouble getting to some stuff so i am taking the easy way out
Code:
private static var _interrupted:Boolean;
public static function setInterrupted(value:Boolean):void{
_interrupted = value;
}
How would you go about calling the public properties and methods of a SWF you load in actionscript?
I have been using stackoverflow for years to answer my programming questions so I wanted to give back by writing a guide to an issue I had a lot of trouble figuring out. This is my first user guide so tell me if there is anything I can do to improve it.
If I created a static method. say I decide to call on other methods within that static method. Do those methods I call on need to be static as well? what If I used some of the properties. Not to store data permanently, but just within that process. Do those properties need to be static ??

To my knowledge this doesn't break Liskov's Substitution Principle as an instance of a subclass can do all the things that an instance of a superclass can do.

I have a class called (DropDown.as)In that class I haveCode:public static const DROPDOWN_CHANGE:String = "Drop Down Changed";In my document class (Main.as) I instantiate my class and try and trace my public static constant but it outputs undefined:

So the reason I'm asking is..I have like 2000+ lines of code in 5 different separate classes. And they ALL have public properties and methods (as in, ALL the properties and methods are public). This is a fairly complex tile game 2d platformer. And yet everything is working fine. From what I've read, it seems that it 'MAY' cause problems later, where you might make a mistake and call a property twice, or call it 'wrongly', which then 'MAY' cause a bug that would be hard to backtrack.
There are surely many other reasons why not to do this..but if everything is working smoothly so far, should I really go back and try to make every variable private and recode this engine before I get to far?
I'm setting up a class of public static vars that are to be BitmapData.
The problem I'm having is I can't seem to reference the vars dynamically in an array, making it impossible to give them values without some serious procdedural style coding.
This is what it looks like
package com.myPackage{
import flash.display.*;
import flash.events.*;
[Code]....
Should I assume it's because my array is a private var and placing references to public static vars is illegal? Is somebody gonna call the flash police on me?

View 6 RepliesThis might be a very stupid question, but I have to ask it anyway. I am graduating in about a month and while studying, I have always been taught to use properties instead of public variables. So I started wondering what the advantage was and I must say that in some cases, I have no clue at all. Of course it is handy when some other logic needs to be executed when setting properties or getting properties, but is there any advantage to using properties when you are only getting/setting a variable? An example of what I mean is shown below (As3).

I have a custom button with a textfield inside:
package com.company.utils.ui

playButton.label.text = "myText";
I have tried declaring an interface with static methods, but I'm getting an error:
PHP Code: 1157: Interface members cannot be declared public, private, protected, or internal.
I have about 3 different classes I'd like to implement this interface and there are only two static methods that I want to define. If I remove the public and static keywords in my interface, they must also be removed from the classes or it complains about that:
PHP Code:1044: Interface method serialize in namespace net.foo:MyInterface not implemented by class net.foo:MyClass.
So I guess I should just dispense with the interface?
I'm working on a video player and I initially developed the player with everything in the .FLA file with no classes. Then I started modularizing my player into classes and realised that my classes are static methods rather than instance methods which doesn't seem to be needed in my player. My question is - is this a bad design to have all of your classes methods to be static rather than instance methods ? As I dont see the need (yet) so that's why i geared more towards static methods, is this a bad design?
